Use of uncertified seeds can reduce soybean crop **Translation:** The use of uncertified seeds can reduce the soybean crop.

The soybean market in Brazil faces a warning scenario with the spread of the use of uncertified seeds, which can directly affect the productivity of the 2025/26 crop and impact exports. According to data released by CEEMA, the use of uncertified soybean seeds — including pirated and irregularly marketed saved seeds — already reaches 27% of the cultivated area in Brazil, equivalent to 13 million hectares.

Of these, 1.9 million would no longer be exported and another 900 thousand tons would affect domestic consumption. In addition, the seed market loses about R$ 8 billion with the reduction in sales, and the loss in genetic royalties reaches R$ 590 million. The practice compromises investments in ...
